SOLAR WATER HEATING SYSTEMS Hydronic System Analysis Closed loop – Active system Potable water routed to storage tank Working Fluid circulates through collectors Potable water is heated through heat exchanger System requires auxiliary components like expansion tank, valves, etc.

BASIC ILLUSTRATION

MAJOR COMPONENTS ANALYZED analysis & selection of suitable pump selection of appropriate heat exchanger selection of main water storage tank. primary plumbing components – pipes For Each: options, benefits and costs analyzed

HYDRONIC SYSTEM PUMP ANLAYSIS How the analysis was carried out : 1. Design analysis was based on Architectural & Solar Thermal systems & options were considered 2. Architectural: basement & overall house dimensions 3. Solar Thermal: two possible options of Flat Plate Collectors with varying flow rates, dimensions and pressure losses. 4. Result of Total System Head Loss : No. of FPC’s 4 4 Flow Rate (GPM) 0. 35 0. 52 Pressure drop (Psi) 0. 87 4. 86 Cumulative Head Loss (Ft) 6 14

OPTIONS FOR MAIN PUMP Grundfos UP Series Circulator Stainless steel protects against corrosion 3 Speed Super-Brute technology Integrated removable check valve Highest starting torque in its class Quick connecting terminals 3 yr warranty Cost: $200 -$400

PVC @ $2

Flat Plate Solar Collector – Sunmaxx M 2 Thermal f-value Output

Flat Plate Solar Collector – Sunmaxx M 2 21. 53 ft 2 aperture area 0. 35 gpm flow rate Lower cost Smaller surface area and slower flow rate produce less hot water than SH Would handle 39. 4% of hot water needs

Flat Plate Solar Collector – Enerworks SH 10 US Thermal f-value Output

Flat Plate Solar Collector – Enerworks SH 10 US 28. 97 ft 2 aperture area 0. 52 gpm flow rate Higher cost Higher flow rate and larger surface area produce more hot water than M 2 Would handle 47% of hot water needs
